Learn more about Klarna
Carmex Carbide Threading Insert is a versatile, TiAlN-coated solution designed for machinists who need reliable performance across a wide range of ISO and metric thread profiles. Built for both internal and external threading tasks, it delivers consistent results with a single, easy-to-manage insert family.
- Lengths: 5 available lengths, from 12 mm to 40 mm, to fit standard threading operations and tooling setups.
- Coating: TiAlN-coated carbide for enhanced wear resistance and heat tolerance, extending tool life in demanding turning and threading applications.
- Double-sided edges: Two cutting edges per insert (except for BSPT/NPT/NPTF/American Buttress/API RD profiles), providing additional use before indexing.
- Broad profile coverage: Designed to cover all common thread profiles, simplifying tooling inventories and setup.
- Internal & External threading: For many thread profiles, the same insert can machine both internal and external applications, saving time and components (note exceptions for ISO/UN/NPSM/UNJ/Acme).
- Rigid carbide construction: Precisely engineered for stable performances in medium- to high-speed threading operations and tough materials.
This threading insert family is ideal for shops that need a single, reliable solution across diverse projects—whether upgrading existing tooling or standardizing on a robust insert set. The TiAlN coating lowers wear, maintains cutting precision, and supports longer runs between tool changes. With multiple lengths and the convenience of double-edged geometry, you can adapt quickly to varying thread forms and production demands, keeping cycles efficient and output consistent. Practical use cases span mechanical assemblies, automotive components, and general fabricating tasks where accurate, repeatable threads are essential.
